I've already linked you a story debunking this assertion in another thread but here’s another one:
Primatologist, Meredith Small has noted that “seeking novelty is the single most observable trait among all the sexual behaviors, preferences, and drivers of female primates. Female primates are actually the complete opposite of how we’ve been taught to imagine them — as reluctant breeders or seekers of “intimacy” with a single “best” mate or only seeking to mate with the alpha.” (Untrue, pg. 165) I’m not sure why we imagine that human primates are any different absent a culture that does not allow for that.
In reality, amongst all animals, “A female who mates with several different males will have more genetically diverse offspring, boosting the chances that at least some of them will thrive.” Source There is little true monogamy in nature, and even animals who nest together may have offspring sired by more than one male.
When Darwin observed that females of many species were naturally coy and choosy and reticent, sexually speaking, and males were naturally competitive and randy, he set us on a course by distorting the lens through which we view behavior. What we know today thanks to mostly female primatologists, anthropologists, and sex researchers is that when the context is right, female sexuality is assertive, adventurous, and what we call “promiscuous.”
The great anthropologist and comparativist Sarah Hrdy tells us that, across species, including among humans, the best mother for many eons was the one who was, under particular and far-from-rare ecological circumstances, promiscuous. By being so, she could hedge against male infertility, up her odds of a healthy pregnancy and robust offspring, and create a wider network of support by lining up two or three males who figured the offspring might be theirs.

In a violent, misogynistic rape culture, women have to be more concerned about their safety, their reputation, and unwanted pregnancy but for most of human history, that wasn’t the case. Pretending that modern dynamics within a patriarchy — a social system that has only existed for about 5k years — tell us anything at all about “human nature” or how women “naturally” are is just delusional.
